We have been using zerocuity services for over 2 years now with no issues to report so far (we had some minor ones in our first year but they were quickly resolved). I like their proactive approach to keeping us informed of any changes or updates to their products. Their customer support team also gets my vote as being very responsive when we need help! The only thing would be if there was an option to integrate more than one device into the same account - this could easily be accomplished however. Security management at scale via API's for multiple customers who are all utilizing different devices and applications.
